Help! 10.04 LTSP configuration using only one nic

[Jim Christiansen]

Hi Dave.  Looking back I haven't found any evidence that  /etc/ltsp/nat has
been altered since issuing sudo sh -c 'iptables-save > /etc/ltsp/nat', nor
do I know how to alter the networking interface to use the change- but- I
have been wondering if this somehow, is what is causing the slow-down.

Clients wouldn't boot from the server before issuing those two commands.
 They did afterwards, but not reliably.  Should I install a second nic on
the system then re-install ltsp??  I wonder... if I should buy gigz switches
or reinstall ltsp using 2 nics...  Maybe a gig switch or two to start would
be easiest.

Do ltsp fat clients work on 100 megabit networks or are all of the installs
in schools use gig networks?

Thank you for taking time to think about this.

Jim

-----------------
You don't mention if you also then alter the networking interface to include
using the /etc/ltsp/nat file but I thought this setting was for port
forwarding in a 2 NIC setup. e.g. thin clients on 192.168 subnet with the
main network on say 10. so that local apps like firefox would work
correctly.  see:
https://help.ubuntu.com/community/UbuntuLTSP/ThinClientHowtoNAT

I don't see how port forwarding would be useful for a single NIC with Fat
clients.  With only a 100Mbit link, I'd think that it could get overloaded
once you get several clients mounting the image. Do you have a switch with a
gigabit port for the ltsp server available?
